[PATCH BlueZ] device: Fix airpods pairing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


Apple Airpods are discoverable and pairable in BREDR mode, but also
advertise in unconnectable mode in LE with the same Public address, at the
same time. As the pairing process uses the latest seen address, sometimes
it uses the LE Public address to pair, which fails.

This commit introduces the connectable state when selecting the bearer to
use for a connection. The last_seen value is used only for connectable
